Here's info from shocktillyoudrop.com:
"Hoo-boy. Warner Home Video announced it has set a May 20th street date for Ken Russell's infamous The Devils. Purists will take no pleasure in learning there are no extras. They should, however, note Warner is presenting an uncut version (at 111 minutes in length). Released in 1971, the film stars Oliver Reed, Vanessa Redgrave, Gemma Jones and Dudley Sutton."
